Abstract: ABSTRACT OF THE DISCLOSURE A power braking apparatus having a housing with a cavity therein through which a fluid under pressure is continually flowing.  A piston separates the cavity into an inlet chamber and an outlet chamber. The piston has a passageway for connecting the inlet chamber from the outlet chamber.  A valve in the passageway is adapted to regulate the flow of fluid from the inlet chamber to the outlet chamber.  A disc located in the stem of the valve resiliently biased against a head on the stem.  One side of the disc is connected to the inlet chamber and the other is connected to the outlet chamber.  An actuation input moves the valve toward a seat to restrict the flow of fluid between the inlet chamber and the outlet chamber and establish a pressure differential therebetween.  This pressure differential will move the piston to provide an output force.  When the pressure differential reaches a predetermined  value, the resiliently biased disc on the stem will move away from the head to prevent the complete interruption of flow between the inlet chamber and the outlet chamber.

Abstract: RACK AND PINION POWER STEERING GEAR           ABSTRACT OF THE DISCLOSURE A rack and pinion power steering gear is disclosed which includes a manifolding arrangement to eliminate external fluid connections between the power steering valve and the cylinder.  The manifolding arrangement includes a tube which is received within the steering housing.  The diameter of the tube is less than the diameter of the housing in which the rack is received so that an annular fluid passage is defined between the outer circumferential surface of the tube and the inner circumferential surface of the housing. The annular passage communicates fluid the entire length of the rack mechanism, so that fluid may be selectively admitted to opposite sides of the piston depending upon the direction which the vehicle wheels are turned.  The manifolding mechanism further includes a sleeve which extends into the tube and which is provided with passages extending there-through to communicate fluid pressure to the other side of the piston.          The sleeve also serves to seal against the rack to prevent fluid from leaking from the hydraulic cylinder.  The entire manifolding arrangement is designed so that the same basic housing may be used for either power or manual rack and pinion gears, the manifolding arrangement being added to provide a power assist without any substantial change in the machining or design of the housing.

Abstract: Abstract of the Disclosure A vertical synchronization (sync) signal detector for use in television reception is disclosed.  From a T.V. video signal a composite sync signal comprising horizontal sync pulses, vertical sync pulses and equalizing pulses is removed.  A phase controlled oscillator senses when all of these three signals which make up the composite sync signal are constant.          Since only the vertical sync signal will be low during such 'constant' periods the starting point of the vertical sync pulse can be located.  Thus, the phase controlled oscillator is arranged to generate timing pulses during such 'constant' periods and these timing pulses are used to control a samp-ling circuit which samples the composite sync signal and thereby separates the vertical sync signal.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides an apparatus for zone refining polycrystalline semiconductor rods to produce mono-crystalline semiconductor rods.  The apparatus permits the processing of larger diameter rods, and longer rods, without unduly increasing the overall height of the apparatus.  The apparatus is provided with an induction  heating chamber in which the longitudinal dimension is not determined by the length of the rod to be refined, but rather is limited only by considerations of space for the RF coil and related apparatus which must be mounted in the chamber, viewing space for the operator and the heating effect on the structure above and below the chamber.  The semiconductor rod extends above the induction heating chamber initially and below the chamber at the conclusion of the refining process. An upper metal bellows extends from the top of the rod holder to the top of the chamber and a similar lower bellows extends from the bottom of the seed holder to the bottom of the chamber.  A telescoping group of steel cylinders are placed inside the lower bellows to protect the lower bellows from any molten semiconductor which may drop from the melt zone.          The telescoping group of steel cylinders surrounds the seed holder and the largest of the cylinders is attached in common with the lower bellows to the induction heating chamber and the smallest is attached to the base of the seed holder.

Abstract: FLUID CATALYTIC CRACKING PROCESS                            ABSTRACT      An improvement in the fluid cracking process is obtained by contacting the hydrocarbon feed in a riser reaction zone first with a recycled coke-containing spent catalyst and then contacting the resultant mixture with freshly regenerated catalyst to produce the desired conversion of the hydrocarbon feed and a coke-containing spent catalyst, a portion of the spent catalyst being recycled without regeneration to the inlet of the reaction zone and the remainder being regenerated and returned to an inter-mediate point in the reaction zone.  The recycled coke-containing spent catalyst has sufficient activity so that the highly reactive nitrogen and carbon residue containing hydrocarbon contaminants in the oil feed will deposit on the spent catalyst and thus mini-mize the deactivation of the freshly regenerated catalyst used in the subsequent cracking of the oil feed.      By contacting the oil feed first with the recycled spent catalyst, this invention allows the refiner to utilize the full activity and selectivity characteristics of the freshly regen-erated catalyst in order to obtain higher yields of the desired products from the cracking operations.

Abstract: ABSTRACT                      Phase comparison apparatus, for example for use in phase lock loop (PLL) systems, comprises a first and a second phase comparator. The first comparator has a high gain (e.g. 1000) and a narrow phase difference range (e.g. 5°) and the second phase comparator has a substantially greater range (e.g. 720°). The second phase comparator is automatically switched out when the apparatus is operating in the narrow range and the outputs of the two comparators are proportionately combined in such a way that the combined output characteristic is linear over the whole range covered by the apparatus. The lock-up time of a PLL system using the apparatus is reduced by 10 to 100 times and system noise due to the apparatus can be reduced to negligible proportions.
